Exactly which layer is another issue; for example I wouldn't use the Courtyard Layer since in the future someone may want to implement formal collision tests on Courtyard outlines. There are also any number of ways to accomplish the goal - for example you can place a small target mark on the Silk Layer and that serves as a placement reference for a generic mechanical model, or you can put a target mark as well as an outline box to show the actual mechanical extent of a specific mechanical component. - Cirilo > ________________________________________ > From: easyw [[email protected]] > Sent: 25 February 2016 16:35 > To: Mário Luzeiro; Wayne Stambaugh; [email protected] > Subject: Re: [Kicad-developers] VRML export > > > How does the other ECAD deal with that case scenarios?
